Would you eat Genetically Modified Salmon?

While the debate over whether to label foods containing GMO ingredients plays out across the country, another engineered food has long been waiting to hit grocery stores: genetically modified salmon.
What is the value of bees?
June 21, 2015 09:55 AM - Steve Williams, Care2
What are bees worth to our economy? A group of researchers have attempted to do the math, and the result shows exactly why we need to protect our pollinating bees but also why we can’t rely on economic worth alone to make our arguments for saving threatened species.
It may sound slightly abhorrent to put a price on a living creature–and, to an extent, it is. But calculating the monetary worth of wildlife and, in particular, their place in the overall economy has become a useful way for researchers to communicate to governments and even businesses that they need to take a closer look at preventing species die-out. When it comes to bees however, researchers have found an interesting fact that they say shows the worth and the shortcomings of this approach.
US has more oil spills than you think
June 18, 2015 06:47 AM - Roy L Hales, ECOreport
The US has more oil spills than we thought and the number doubled after production increased six years ago. Richard Stover, PhD, and the Center for Biological Diversity counted nearly 8,000 significant incidents, between 1986 and 2014, in records of the pipeline safety administration. By “significant” they mean causing injury, death, damages exceeding $50,000 in value, a loss of 5 barrels of highly volatile substances, 50 barrels of other liquids or there was an explosion. There have been more than 500 human deaths and 2,300 injuries through-out that period. The number of plant and animal casualties is much higher.
Pacific Fisher needs protection
June 12, 2015 07:58 AM - Center for Biological Diversity
In response to a petition and lawsuit from the Center for Biological Diversity, the California Department of Fish and Wildlife today recommended state Endangered Species Act protection for the fisher in the southern Sierra Nevada portion of its range.
Though this cat-like member of the weasel family was once wide-ranging, today only two naturally occurring fisher populations survive — one in the southern Sierra and another in Northern California. The department did not recommend protecting the fisher’s northern population. The state Fish and Game Commission will vote in August on whether to finalize protection for one or both populations.
Spider and Centipede Venom Could Help us Fight Pain and Cancer
June 12, 2015 06:53 AM - Science/AAAS
Certain spiders and centipedes—despite being separated by more than 500 million years—have independently evolved the same type of venom from an insulinlike hormone. The find, reported today, could lead to greener insecticides and potentially help fight chronic pain and cancer.
How Pigeons organize for better navigation
June 10, 2015 07:35 AM - University of Oxford
Having a hierarchical social structure with just a few well-connected leaders enables pigeon flocks to navigate more accurately on the wing, new research shows.
Hierarchical organisation also enables flocks to cope better with navigation errors made by individual birds.
Researchers from Oxford University and the Zoological Society of London created 'virtual flocks' of homing pigeons to test how different social networks affect the navigation performance of these groups. The team's simulations looked at everything from no networks (all connections between individuals were of equal strength) to random networks (some connections were stronger than others but randomly distributed) to hierarchical networks with just a few well-connected individuals leading the way.
Ladybird colors and toxicity to birds
June 5, 2015 07:31 AM - Lina María Arenas, Dominic Walter and Martin Stevens, University of Exeter
For one of Britain’s best-loved and colourful group of insects, ladybirds, their colour reveals the extent of their toxicity to predators, according to new research undertaken at the Universities of Exeter and Cambridge.
The study which is published today in the journal Scientific Reports, also found that the more conspicuous and colourful the ladybird species, the less likely it is to be attacked by birds.
El Niños and Bunny Booms
June 4, 2015 09:01 AM - University of Utah
At times during the past 10,000 years, cottontails and hares reproduced like rabbits and their numbers surged when the El Niño weather pattern drenched the Pacific Coast with rain, according to a University of Utah analysis of 3,463 bunny bones. The study of ancient rabbit populations at a Baja California site may help scientists better understand how mammals that range from the coast to the interior will respond to climate change, says anthropology doctoral student Isaac Hart. He is first author of the study to be published in the July issue of the journal Quaternary Research.
Connecting Elevation and Evolution
June 3, 2015 09:37 AM - Brown University
About 34 million years ago, global temperatures took a dive, causing a sudden wave of extinctions among European mammals. In North America, however, life went on largely unscathed. A new study explains why: The rise of the Rocky Mountains had forced North American mammals to adapt to a colder, drier world.
